Hi Tim: You might look into the DS3232 which can be combined with a PIC to control the aging rate register. http://www.maximintegrated.com/datasheet/index.mvp/id/4984

Hi all, I'm a time nut newbie. My obsession started with the search for an accurate chronometer to carry on my boat for celestial navigation. Yes there still are a few of us left that practice the art. My current project is a quartz chronometer using a DS32Khz tcxo oscillator and two 74HC4060s (+ or- 10 seconds / year). For my next project I'm looking at an Abricon Part Number AOCJY2-10.000MHZ ocxo 5 ppb running through a pic and using the algorithm posted on http://www.romanblack.com/one_sec.htm. I'm shooting for + or - 1 seconds / year. Is there an archive of old posts that might be helpful in answering some of my questions and for getting ideas.
